To LtZZ whom it may concern:

Be it known that I, HARRY ROBERTSON, a citizen of theUnited States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Apparatus for Dispensing Carbonated Liquids, of which the following is a specification.

ratus fordispcnsin g water, soda, or otherbev erages charged with carbonic acid or other gas into bottles or other receptacles; and its objects are, among others, to provide a ready and efficacious means whereby the said liquid may be drawn from the tank or reservoir in which it is contained underpressure and dispensed without losing the gas with which impregnated or causing foam; and it consists in the combination of parts and arrangements of details hereinafter described and claimed, and illustrated in the accompanying drawing, which is a plan View of a dispensing apparatus embodying my invention.

A represents a tank or reservoir containing liquid charged with gas under pressure. It is provided with a single opening and communicates with the chamber 0 through the pipe D, which has a valve K near the point where it enters the said chamber. This chamber O is provided with a water-gage 0 but it may, however, be. constructed entirely of glass, so as to enable the operator to accurately observe the amount of liquid therein.

Directly above the chamber 0 and communicating therewith through the pipe D is the top-pressure-reservc chamber 0, having a pressure-gage c and a small valve 0 at its top to admit of the escape of gas or air therefrom when desired. The pipe D 'is provided with a valve K intermediate the chamber 0 and the pipe D This pipe D leads from the chamber C through the lower part of the pipe D to the chamber 13 and is controlled by the valve K The chamber 13 has a small valve Z) at its upper part for the purpose of allowing the inlet or outlet of air or gas to or from the said chamber.

At the lower end of the chamber 0 and adjacent to the point where-the pipe D enters is the discharge-pipe D controlled by the valve K through which the liquid passes into thebottle or other receptacle. I 1 I For the purpose of more readily operating the valves I have provided the lever E, fulcrumed at its lower end and provided with a handle e at its upper end ahd having pivotally-connected arms E F and supplemental arms F and F secured to the said lever intermediate the said handle and fulcrum by means of the rod E. These arms pass through slots in the ends of the valve-arms k and are provided with pins f F and E on one side of the valve-arms ahd F and F on the op'posite side-so that by movement of the lever in one direction the pins on the arms F and F passing through the arms of the valves K and K will engage the same, and by move ment in the opposite direction the arms of the valves K and K willbe' engagedby the pins on the arms F and F thus affording means for opening the two sets of valves alternately, the upper valve in each instance a little in advance of the lower one. The valves are held normally in a closed position by springs attached at one end to the valve-arms and at the other to a stationary pin, to which position each one will return as soon as the pressure of the pin is released.

The operation of this device is as follows: When it is desired to draw off a quantity of the liquid from the tank' A and dispense it into a bottle, glass, or other receptacle, the valve K is first opened by pressing the lever B backward, allowing the gas in the chamber C to enter the chamber 0, thus causing a pressure in the two chambers considerably less than the original pressure in the chamber C, the amount of which is indicated by the pressure-gage c at the upper part of O. The valve K, leading from the tankA to the chamber 0, is then opened by pressing the lever still farther backward, and the liquid in the tank A will then pass upward into this chamber 0 against the pressure therein and will be prevented by the resistance of this pressure from violent agitation and foaming and consequent loss of the gas with which it is charged-to any appreciable extent. As the chamber 0 becomes filled with the carbon ated liquid the top pressure will be forced upward into the chamber 0' above, and after the desired amount of liquid has been drawn from the chamber A into the chamber 0 the valves K and K are closed by releasing the lever, thus cutting oif all communication between the chamber 0 and the other 'parts of the apparatus. At this stage the liquid in the chamber 0 will of course be still under a considerable pressure and if drawn would become agitated and foam, and thus lose a large amount of the gas with which it is charged. The pipe D is therefore provided for the purpose of allowing this pressure to be relieved, and after the valves K and K have closed the valve K is then opened by pressing the lever forward, allowing the remaining pressure to communicate therethrough with the chamber B and, if it is desired, to entirely remove the pressure through the valve 1) with the open air. The liquid may then be drawn by pressing the lever still farther forward, thus opening the valve K and allowing it to pass through the pipe D into the bottle or other receptacle. The air entering through the pipe D will replace the liquid as it is drawn. The valves K and K may then be closed by releasing the lever, and the operation of dispensing the liquid repeated as often as desired.

It will be readily seen that by the use of this device liquid charged with gas may be drawn in any desired quantity and dispensed at a point above the level of the primary tank or reservoir, being raised to the point of dispensation by the pressure in the primary tank and at the same time prevented from losing the gas with which they are charged while passing into the upper receiving-chamber, the top pressure cut oil and stored for subsequent use, the pressure upon the liquid further reduced or entirely removed, and the liquid then discharged by gravity and with out foaming or agitation.

What I claim is- 1. In an apparatus for dispensing carbonated liquids the combination with a main tank or supply of a secondary chamber communicating therewith through a valve, a top-pressure chamber and a third chamber each coinmunicating with said secondary chamber through valves and being provided with a valve to admit comm u nication with the outer air, and an'outlet for liquid from said secondary chamber.

2. 111 an apparatus for dispensing liquids charged with gas, the combination of a primary receptacle communicating with a secondary receptacle through a valve-controlled outlet, a top-pressure chamber communicating with said secondary chamber through a valve and a valve for allowing the entrance or escape of gas or air to or from said secondary chamber, and a valve for allowing the outlet of liquid from said secondary chamber, all of the aforesaid valves being operated by a single lever, the movement of which in one direction opens the valves between the primary receptacle and secondary receptacle and secondary receptacle the top-pressure chamber, and themovement of which in the opposite direction opens the said gas or air escape and the liquid-outlet valves.

In testimony whereof I have hereunto set my hand, this, 0th day of May, 1898, at the city of New York, N. Y.
